African American population partitions. African American population partitions for all 1000 haplotypes are shown. Block algorithms are abbreviated as HB (HapBlock), GA (Gabriel's method), MD (MDBlocks). The first two tracks show resulting block partitions from HapBlock and Gabriel's method using all SNPs. Next set of three tracks display resulting block partitions using all SNPs with a 10% MAF. The shared blocks track shows chromosomal regions common to all three block partitions using SNPs with a 10% MAF. The last two tracks show SNP positions of all SNPs and SNPs with at least a 10% MAF.
